The 4 ports mean that one can plug in their phone, tablet, battery power pack, and their significant others

phone and charge all of them at full speed. All four ports output at 2.4A( amps). It will take an input of 12-18V

depending upon the vehicle and the output the vehicle is rated at.

It comes in a very sleek looking black with aluminum accents so it blends in nicely with the car's interior.

There is a subtle blue LED, visible in the top most USB port so you can find it in the dark. A word of warning

with the LED, it is not very bright. When I say(write) subtle I mean that it is subtle.

Because of the number of USB ports, this unit is a little wide. It is also a little longer than most DC outlets. This charger will stick out a little farther from the DC outlet than other chargers. I have another, single USB port charger that sits just a little from the outlet, so you can grab it. This one will stick out much farther and potentially get in the way. Since it is wider and longer than most other car chargers, make sure you have enough room for it.

Overall, this is a very nice charger. I would gladly recommend this to anyone looking to get more ports

for their vehicle so they can charge all their devices. My wife loves it, so I love it!

PROS: All 4 ports output at 5V 2.4A

Very clean looking

Wide enough to accomodate the 4 ports
